PRIMER FOR GASOLENE-ENGINES.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed January 29, 1909. Serial No. 475,076.

To all whom it may concern;

Be it known that I, CHARLES E. ARNOLD,

of Indianapolis, county of Marion, and State of Indiana, have invented a certain useful Primer for Gasolne-Engines; and I tofore measuring means have been pro-- vided in the priming tank, or in connection with it and remote from the cylinder of the engine.

The chief feature of the invention consists in providing a. valve for controlling the supply of gasolene to the'engine for prim-= mg purposes, which valve measures, in a way, the quantity of gasolene that is permitted to pass to the engine. During the throw or operation of the valve it temporarily opens a passage way for gasolene intermediate the limits of movement of the.

valve, and during such temporary alinement of the port through the valve and the passageway for the gasolene, a suliicient quantity of gasolene fiowsthrough the valve to the'engine, to serve for the purpose of priming. By measuring the charge of gasolene with thevalve, said valve or measuring de- 1 vice may be located comparativelynear the v so as to beimmediately and completely cylinder of the engine and the gasolene stand normally close to the cylinder so that the charge passes suddenly and almost directly to the cylinder, at least, to the intake pipe,

drawn into the cylinder. In carrying out the foregoing feature of the invention a gasolcne tank is mounted on the dash board of the automobile and a tube leads therefrom to short tubes con nected with the intake pipes and the valve is located at the end of the tube leading from the gasoleno tank that'lies nearest the cylinder of the engine, so normally the gasolene does not stand entirely in the. gasolenc tank but also in the pipe leading to the valve and, therefore, it stands normally at the valve and ready to pass in on the instant the valve is operated.

Another feature of the invention consists in discharging the charge of gasolene for priming purposes into the intake pipe and also having the tube from the carburetor into the intake pipe so that air will be furnished through the carbureter to mix with the gasolene constituting the priming charge and the mixing will take place in the intake ipe. v

- Another feature of the invention consists in combining with the gasolene tank for priming purposes means for compressing air therein so that the gasolene will be normally under pressure sufficient to suddenly and completely force the charge of gasolene through the valve, when it opens the passageway, and no feature in the operation'of the device is left to uncertainty or lack of positiveness.

The nature of my invention will be understood from the accompanying drawings and the following description and claims.

In the drawing Figure 1 is a side elevav tion of the forward portion of an automobile with parts in section and other parts broken away. Fig. 2 is a central vertical section through the gasolene tank, the an compressor and the portion of the dashboard to which they are secured. Fig. 3 is a side elevation ofthe measuring valve and the associated parts, showing the measuring valve in its unoperated posltlon. Fig. 4 1s a transverse central vertical section through Fig. 3. Fig. 5 is the same as the lowervpart of Fig. 3 with the valve mechanism actuated.

Figs. 6 and 7 are vertical sections through the lower parts of Figs. 3 and 5, but VIQWGd from an opposite standpoint.

In the drawings herein 10 represents the frame of an automobile, 11 the dash board, 12 the radiator, 13 the cylinders of the engines, there being four of them, and 14 the hood covering the engines. The cylinders. of the engines are arranged in pairs, each. pair being connected by an intake pipe 15 so that there are in the drawing shown two such intake pipes. A pipe 16 runs from the carbureter 17 to said intake pipes. The connection between pipe 15 and 16 is preferably about midway of the intake'pipes asshown. On the dash board a gasolene tank 20 is secured for containing gasolene for primingpurposes. There is also an air pump 21 secured on the rear side of the dash board and in'communication with the upper end of the gasolene. tank whereby air may be comressed in said tank for forcing out the gasoene. A pipe 22 leads from the lower part of the gusolene tank to-a .valve mechanism 'mingles with air through the pipe 16.

23- mounted in connection with the middle portion of a pipe 24, below the hood, that connects with the middle of the intake pipes 15. Theretore, it is observed that the gasolene stands under pressure in the-gasolene tank and in pipe 22 right down to the valve mechanism and ready to issue through said valve mechanism when the valve permits it. Hence, this construction brings the gasolene close to the cylinder of the engine, for as the valve mechanism is operated the charge of gasolene passing through will be immediately drawn to the proper cylinder according to the relative position of the piston in the diiierent cylinders, then the charge of gasolene is thus immediately thrown from the valve mechanism and drawn into the proper intake pipe where it at the same time drawn from the carbureter The gasolene and air which thus have entered the intake pipe mixes and immediately enters the proper cylinder.

While I have shown four cylinders the invention is not limited to any particular number. The smaller the number of cylinders, the closer to the cylinders the valve mechanism 23 may be placed. Thus if there be only two cylinders the valve mechanism would be located adjacent to the intake pipe 15.

Coming now measuring valve mechanism 23, it' is in detail as shown in Figs. 8 to 7. A valve casing which is secured to pipes. 22 and 24 has a port or passage way 30 through each end thereof with which the ports 31 in the valve 32 are adapted to register at times. This valve is a-t'our way valve tapering and fitting snugly in the casing. It is actuated bythe lever33 with which a cord 34 is connected;

During such actuation the ports register temporarily and then the gasolene passes from pipe 22 through pipe 24 into the intake pipe, very suddenly. The registry of these ports is but for a moment. The valve is moved in the same direction at each operation thereof; therefore, on the end of the to the construction of the 35 on the lever 33 is adapted to engage a eachoperation of the lever, the lowerreturned to its normal position by the srp'ing valve there is a ratchet-4A with which apawl 36. The backward movement of the ever does not move the valve but merely moves the pawl into engagement with a'successive ratchet tooth in order that the valve may be given another partial revolution. Hence, the valve movement is step by step, herein having but one-fourth revolution at each actuation and stopping always with the ports so that the conduit Wlll normally be closed. The spring is a flat one fastened at one end to a pin 38 on the casing and at the other end to said lever. The return movements of the lever are limited by a stop 39 on the casing.

\Vhat I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a gasolene engine cylinder, of a conduit for supplying gasolene thereto for priming, a rotary valve in said conduit provided with ports at intervals, and means for giving said valve a partial rotation at each operation thereof,

whereby the valve will close'the conduit at the beginning and ending of-each operation and will open the valve-temporarily during the operation.

2. The combination with a gasolene engine cylinder, oi a conduit for supplying asolene thereto for priming, a rotary valve in said conduit with a plurality of ports therethrough, a ratchet in connection with said valve w1th teeth corresponding with the ports, an oscillating lever for engaging said ratchet and actuating the valve for a partial revolution, and a spring for return-' ing said valve actuating means'to its normal position.

In witness whereof, I have hereunto aflixed my signature in the presence of the witnesses herein named.
